  • Patent number: 4671633
    Abstract: The invention relates to a slide magazine with housing, open at the top, a slide projector with a picture-changing device having a horizontally actuated slide pusher. The housing, which can be mounted immovably in the projector, has, approximately in the longitudinal center of a longitudinal wall, an opening for a slide, opposite which there is a deflector with a deflecting surface, which runs at an angle to the longitudinal center plane of the housing. In the area of the deflector, a transporting lever, which can be moved transversely to the longitudinal center plane from a resting position to a working position, and which has a working surface that works together with the slide pusher, is mounted especially so that it can be swivelled. With the transporting lever in the resting position, the working surface protrudes into the path of the slide pusher. However, when the transporting lever is in the working position, the working surface is arranged outside of this path.

  • Patent number: 4382664
    Abstract: Apparatus is disclosed for viewing photographic slides carried in a long magazine by a slide projector which is configured to accept only a circular slide magazine or carrousel. This invention provides a simple and efficient mechanism for using long magazines with a circular magazine projector without the need of first transferring by hand all of the slides from the long magazine into a circular magazine. An attachment adapted to be fastened to the projector housing has a covered channel for accepting and advancing a long magazine inserted therein. Adjacent the long magazine within the attachment is an intermediate storage tray which contains slide compartments and which is moved synchronously with the long magazine. Slanting guide rails extend from the long magazine to the intermediate storage tray, and these rails individually transfer the slides from the long magazine into the storage tray as the long magazine is advanced.

  • Patent number: 4317619
    Abstract: A microfiche reader and/or enlarger has a housing provided with an opening. The microfiches are stored in hard-cover files having a pair of covers between which a series of pockets is located, with the individual pockets being connected to one another and the two end pockets each being connected to one of the covers. When the covers are moved from parallel to coplanar position the pockets assume a fan-shaped outline; when the file is attached to the opening in this position with the pockets projecting into the housing, inner open ends of the pockets are accessible to a gripper on a pivot arm which can be moved opposite any selected one of the open ends. The gripper can then extract the microfiche from the selected pocket and subsequently reinsert it thereinto.

  • Patent number: 4204754
    Abstract: A number of format films carrying fixed information to be recorded together with computer output information given by a magnetic tape are vertically stacked in a cassette. The cassette is supported on a vertically movable cassette support. At a predetermined level which is of the same level as a projection station where the format film is brought and the image of the film is projected there is provided a format film gripping device. The format film gripping device has a fixed arm and a swingable arm which are opened at the cassette and closed to grip one of the format films in the cassette when the gripping device is driven to take out one of the format films from the cassette and brings the taken out format film to the projection station. The vertically movable cassette support is moved up and down stepwisely to selectively bring one of the format films to be projected to the predetermined level where the format film is taken out of the cassette and brought to the projection station.

  • Patent number: 4169668
    Abstract: The present invention relates to a projector comprising two optical systems enabling transparencies to be projected with cross-fading, in 3-D and with double-width panning, said projector operating with a single transparency distributing and recuperating magazine, in which the transparencies are arranged in the same order as if they were to pass in a single-lens projector; said projector comprises four parallel transparency guide slots, which are parallel to one another and transverse with respect to the axes of two optical systems in which the transparencies circulate in pairs, said guide slots being extended by a switching means whose role is to cause the transparencies which have already been projected to pass from the forward guide slots into the return guide slots, and thus to cause the transparencies to return to the same compartment of the same magazine from which they left. These displacements are possible due to a recuperator having multiple functions.

Preferred motor driven cams (B",R",S",T") act as controls for the stop (8,11) and for slide changing and are operationally timed so that the closing process for the stop is initiated simultaneously or nearly simultaneously with the beginning of the removal of the projected slide (19a) from the slide stage plane and with the insertion of a new slide (19c). The process of stop opening begins immediately and without any pause after the complete closure of the stop which coincides with the terminated insertion of the new slide.

  • Patent number: 4127324
    Abstract: A double slide projector having two slide projection assemblies, a common magazine for slides, and a common slide changer, uses a motion transmitting arrangement from a drive to the changer so that the changer is moved a full stroke for moving slides from the magazine to the more remote projection assembly and the changer motion is blocked at a partial stroke for movement of slides from the magazine to the nearer projection assembly. A drive provides sufficient movement to move the changer for a full stroke for each actuation, and a slip clutch is arranged in the motion transmitting device so that the changer can move alternately between a full-stroke and a blocked or partial-stroke position. A double-track cam is preferred for the drive, and an arrangement of levers connected through the slip clutch is preferred for transmitting motion from the cam to the gripper portion of the slide changer.

  • Patent number: 4053215
    Abstract: Apparatus and a method for handling and reading any one of a number of film strips, each having a number of segments with each segment containing a plurality of information-containing, high-reduction image frames. The film strips are housed in a cassette which is movable with respect to a fixed reference to align a desired film strip with a reading station disposed across the optical path of an optical system. A film strip is moved out of the cassette by a force applied to one of its side edges. Control information carried by each film strip is sensed as the film strip moves out of the cassette and the sensed information is used to control the distance through which the film strip moves so that a particular segment thereof will stop at the reading station. The optical system is moved relative to the reading system so that the optical path of the optical system is selectively alignable with a particular image frame of the film strip removed from the cassette.
